GENERATOR ATTACHMENT MEANS FOR GAS ENGINES.

Patented Jan. 3, 1922.

Application filed October 27, 1919. Serial No. 333,579.

To all whom it may concern:

Be it known that I, HENRY TIEDEMANN, a citizen of the United States, residing at Newark, in the county of Essex, State of New Jersey, have invented certain new and useful Improvements in Generator Attachment Means for Gas Engines, of which the following is a description, reference being had to the accompanying drawing and to the figures of reference marked thereon.

This invention relates to means for attaching generators to internal combustion engines, and as illustrated the generator is for the purpose of supplying ignition to the engine cylinders. It will be understood and agreed that any other type of generator may be used in place of the ignition type for any purpose whatsoever. Theattachment means herein shown and described is particularly adapted for use in connection with a Fordson tractor.

It is the object of my inventionto provide attachment means for an engine of this character which is very simple and inexpensive and which may be readily applied to the said tractor engine by the owner of the tractor.

Other and further objects will be apparent to one skilled in this art after a study of the drawings and annexed specification, wherein- Figure 1 shows a partial side view of the tractor engine with the ignition generator and attachment means in place.

Figure 2 is a view of the attachment plate looking in the direction of the arrow in Figure l but withoutthe ignition generator on the plate.

Figure 3 is an end view of the installation with the cover plate broken away showing the bolt holes in the end of the attachment plate.

Figure 4.- is a partial top view of the cover plate. I

Figure 5 is a sectional view showing the timing shaft, timing gear and driving gear for operating the generator.

eferring now to the details, wherein like numbers refer to corresponding parts in the various views, 1 illustrates the engine cylinders in front of which a radiator 2 and fan 3 are placed. 1 is a bracket having a projecting plate 5 on which a generator 6 is adapted to be fastened in any suitable manner, such as by straps 7. To the ignition generator 6 is fastened an advance lever 41 and an impulse coupling 42 for obtaining hot spark at slow rotative speed of the engine crank shaft. The outer end of the by a brace 8 fastened bottom to one of the regular engine bolts and at the top to the outer end of the plate as by bolt 9 which passes through a slot 44. whereby the bracket 4 can be adjusted as will be hereinafter referred to. The bracket 4 preferably has a web 10 extending under the plate 5 to strengthen and support it. Extending substantially at right angles to the plate 5 is an arm 11 having a bolt hole 12 to receive a bolt corresponding to an established point of attachment on the engine. The arm 11 also has an elongated hole 13 to receive another bolt corresponding to a second established point of attachment on the engine. Extending from the arm 11 is a projection 14: carrying a set screw 15 and lock nut 16, the purpose of which will be hereinafter referred to. At the junction of the plate '5 and arm 11 a bearing block 17 is provided and, as illustrated, the top part of the bearing block 17 has a cover 18 which carries cups 19 for means of lubricating the bearings. The

bearing supports a stub shaft 20 which projects beyond the bearing at one end to receive a coupling 21 of any suitable design,

it being understood that the other part of the coupling is connected to the generator shaft. Carried within the bearing block 17 and cover 18 on the shaft 20 is a sprocket wheel-22 (see Figure 3). The cam shaft 23 hasthe usual gear 24: which engages a suitable gear on the crank shaft and this gear isenclosed within the gear case cover 25.

In order to provide a driving gear from the cam shaft 23 I remove the usual nut which holds the gear 24'in-position on the cam shaft 23 and provide instead a stub shaft 26 which is interiorally threaded to engage the threads 27. The outer end of the stub shaft 26 is adapted to receive a sprocket wheel 28, the same being preferably held to the stub shaft 26 by means of a key 29 and also by means of a nut 30 and washer 31. This means of attaching the sprocket wheel to the cam shaft, I consider to be one of the important features of my attachment means. A noiseless chain 32 connects the sprocket wheel 28 to the sprocket wheel 22 thereby completing the '83 in any suitable manner, such as by rivets 37. The cover 33 carries a stud 38 on which rests the end of a clamp 39, the outer end of which is held to one of the engine studs by means of the hole 40. The clamp 39 is thus used to hold the outer end of the cover in position against the gear case 25, thereby protecting the chem 32 and sprocket wheel 28 from dust, dlrt and other foreign substances.

' As can'be readily seen from an inspection of Figures 1, 2 and 3 the bracket is held onthe engine by means of the engine bolts which normally retain the front gear cover onto the engine block, passing through the bolt holes 12 and 13 and by means of the brace 8 the lower end of whichis held to the flange of the engine by means of one of the bolts that secures the bottom pan of the engine to the engine block. When it is desired to adjust the tension of the chain 32, the bolts passing through the holes 12 and 13 and the bolt 9 are loosened slightly and then the set screw 15, the lower end of which presses against a ledge on the engine block, is adjusted thereby causing the entire bracket to tilt about the bolt passing through the hole 12 as a pivot, the slot 13 in the flange 11 and the slot 44 in the brace 8 being provided so that this tilting may take place without restraint. The bolts are then drawn down thus securing the bracket-in its new position.

In installations of this character a great deal of difficulty is encountered in finding a lace to mount the generator and for proriding a suitable drive for the same, and

*while Ihave shown a preferred form of attachment means for an engine of the type mentioned, I do not wish to be limited to the exact details herein shown and described, except as limited by the scope of the appended claims.
